New proposed censorship policy:
Any post or comment which advocates or 'asks about' violence against sufficiently identifiable real people or groups (as opposed to aliens or hypothetical people on trolley tracks) may be deleted, along with replies that also contain the info necessary to visualize violence against real people.
Reason: Talking about such violence makes that violence more probable, and makes LW look bad; and numerous message boards across the Earth censor discussion of various subtypes of proposed criminal activity without anything bad happening to them.
More generally: Posts or comments advocating or 'asking about' violation of laws that are actually enforced against middle-class people (e.g., kidnapping, not anti-marijuana laws) may at the admins' option be censored on the grounds that it makes LW look bad and that anyone talking about a proposed crime on the Internet fails forever as a criminal (i.e., even if a proposed conspiratorial crime were in fact good, there would still be net negative expected utility from talking about it on the Internet; if it's a bad idea, promoting it conceptually by discussing it is also a bad idea; therefore and in full generality this is a low-value form of discussion).
This is not a poll, but I am asking in advance if anyone has non-obvious consequences they want to point out or policy considerations they would like to raise. In other words, the form of this discussion is not 'Do you like this?' - you probably have a different cost function from people who are held responsible for how LW looks as a whole - but rather, 'Are there any predictable consequences we didn't think of that you would like to point out, and possibly bet on with us if there's a good way to settle the bet?'
Yes, a post of this type was just recently made. I will not link to it, since this censorship policy implies that it will shortly be deleted, and reproducing the info necessary to say who was hypothetically targeted and why would be against the policy.
You seem to be using a very narrow definition of "crypto".. I'm not sure whether you're just being pedantic about definitions, in which case you may be correct, or if you're actually disputing the substance of what I'm saying. To answer your question, I'm not a cryptographer, but I have a CS degree and am quite capable of reading and understanding crypto papers (though not of retaining the knowledge for long)... it's been several years since I read the relevant papers, so I might be getting some of the details wrong in how I'm explaining it, but the basic concept of deniable message authentication is something that's well understood by mainstream cryptographers.
You seem to be aware of the existence of OTR, so I'm confused - are you claiming that it doesn't accomplish what it says it does? Or just that something about the way I'm proposing to apply similar technology to this use case would break some of its assumptions? The latter case is entirely possible, as so far I've put a grand total of about 5 minutes thought into it... if that's the case I'd be curious to know what are the relevant assumptions my proposed use case would break?
If I give you my key, you can pretend to be me on OTR. I've had friends demonstrate this to me, but I've never done it myself, so 99% confidence.
Technical disagreement, as near as I can tell, since you're not advocating for the solution.
